How to display Timer results on next `ViewController´

Question

I have 2 ViewControllers. 1 is for the game which has a timer. Second one is for the results. After pressing finish button on the game ViewController it goes to the result. How can I display the results of the timer on a label on the results ViewController?

This is my code for timer:

//these are initialized in games ViewController.h
IBOutlet UILabel *GameTimer;
int timeSec;
int timeMin;
NSTimer *timer;

//game ViewController.m under @implementation
INSString *timeNow;
NSTimer *timer1;

This is my methods of the timer:

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [self performSelector:@selector(startTimer1) withObject: nil afterDelay:0.0];

}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
-(void)startTimer1{

    //initializing 'timer1'
    timer1 = [NSTimer scheduledTimerWithTimeInterval:1.0
                                              target:self
                                            selector:@selector(timerTick:)
                                            userInfo:nil
                                             repeats:YES];
    [[NSRunLoop currentRunLoop] addTimer:timer1 forMode:NSDefaultRunLoopMode];
}
//Event called every time the NSTimer ticks.
- (void)timerTick:(NSTimer *)timer1
{
    timeSec++;
    if (timeSec == 60)
    {
        timeSec = 0;
        timeMin++;
    }
    //Format the string 00:00
    timeNow = [NSString stringWithFormat:@"Tiempo: %02d:%02d", timeMin, timeSec];
    //Display on your label
    //[timeLabel setStringValue:timeNow];
    GameTimer.text= timeNow;
}
//Call this to stop the timer event(could use as a 'Pause' or 'Reset')
- (void) StopTimer
{
    [timer invalidate];
    timeSec = 0;
    timeMin = 0;
    //Since we reset here, and timerTick won't update your label again, we need to refresh it again.
    //Format the string in 00:00
    timeNow = [NSString stringWithFormat:@"%02d:%02d", timeMin, timeSec];
    //Display on your label
    // [timeLabel setStringValue:timeNow];
    GameTimer.text= timeNow;
}
//executed after the finish button is pressed
- (IBAction)finishPressed:(id)sender{
}

EDIT:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

    LetterResults6x6 *nextViewController = [[LetterResults6x6 alloc] initWithNibName:@"ViewController" bundle:nil]; //Let us assume that ViewController is the controller in which you wish to show the result.
    nextViewController.finalTime = timeNow; //here finalTime is a NSString property in ViewController Class
    [self.navigationController pushViewController:nextViewController animated:YES];
}
- (IBAction)finishPressed:(id)sender
{

    [self performSegueWithIdentifier: @"finished" sender: self];

}

EDIT 2 SOLUTION: I figured it out. I did it in an easier way by adding few lines of code to the timer methods to record the results and then pass them in the other ViewController

- (void)timerTick:(NSTimer *)timer1
{
    timeSec++;
    if (timeSec == 60)
    {
        timeSec = 0;
        timeMin++;
    }
    //Format the string 00:00
    timeNow = [NSString stringWithFormat:@"Tiempo: %02d:%02d", timeMin, timeSec];
    //Display on your label
    //[timeLabel setStringValue:timeNow];
    GameTimer.text= timeNow;
    //code i added
    NSUserDefaults *prefs1 = [NSUserDefaults standardUserDefaults];
    [prefs1 setObject:[NSString stringWithFormat:@"%@",timeNow] forKey:@"keyToLookupString"];
}

then add this to second ViewController .m

NSUserDefaults *prefs1 = [NSUserDefaults standardUserDefaults];
NSString *sc = [prefs1 stringForKey:@"keyToLookupString"];

timerResults.text = [NSString stringWithFormat:@"tiempo %@", sc];

Thanks for all the help guys :)

Answer 1

You should pass the string value to next controller while pushing to it,

If you are using .xib

ViewController *nextViewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil]; //Let us assume that ViewController is the controller in which you wish to show the result.
nextViewController.finalTime = timeNow; //here finalTime is a NSString property in ViewController Class
[self.navigationController pushViewController:nextViewController animated:YES];

For Storyboard, use this code

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.destinationViewController isKindOfClass:[ViewController class]]) {//Let us assume that ViewController is the controller in which you wish to show the result(i.e., Second controller).
        nextViewController.finalTime = timeNow; //here finalTime is a NSString property in ViewController Class
    }
}

EDIT

in first view controller .m file

//executed after the finish button is pressed
- (IBAction)finishPressed:(id)sender{
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender     
{ 
    if ([segue.destinationViewController isKindOfClass:[LetterResults6x6 class]]) { 

    nextViewController.finalTime = timeNow; //here finalTime is a NSString property in ViewController Class 
    } 
}

In LetterResults6x6.h

@property (nonatomic, retain) NSString *finalTime;

In LetterResults6x6.m

- (void)viewDidLoad {
    [super viewDidLoad];
    self.labelOutlet.text = self.finalTime;
}

Answer 2

Just pass the value of your timeSec and timeMin while pushing resultsViewController.

add this Properties in your ResultsViewController.h

@property (nonatomic) int  timeSec;
@property (nonatomic) int  timeMin;

Now in your GameViewController, add the following on this method:-

//executed after the finish button is pressed
- (IBAction)finishPressed:(id)sender{
  ResultsViewController *resultViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ResultsViewController"];
   resultViewController.timeMin=timeMin;  //pass the value
   resultViewController.timeMin=timeSec;  //pass the value

  // now push to your ResultViewController

}
